Yeah, I want to figure out a easy way i can restore some of these 3 ring binders i have, remove the rust, and also get the pages to move more freely on the rusty rings.

There are non damaging chemical solutions like Evapo-Rust Rust Remover, that you can soak the binder area in and remove it. There are also jellies that you can just place on the metal areas to remove it, if youur concerned that there are tears in the binder that will get to the substrate below the surface, which I don't think is plastic on those old binders. Probably cardboard. 1 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 13 Share Posted September 13 The one problem of switching my TI99 systems over from using CRT monitors to VGA screens, is the lack of built-in speakers, so I found these cool vintage looking soundbars, that are just the right size for my 3 systems. This weekend I will make a demonstration video with sound. 6 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 16 Share Posted September 16 One step closer in firing up my USRobotics modems, I got in the power supplies for them today. 3 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 21 Share Posted September 21 A busy retro building week is starting as all the parts are rolling in fast to assemble the first prototype reproduction of the TI99 console. This project will be our OPA breadboard to test out new hardware addons being designed and help improve the TI Operating System as well. 5 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 23 Share Posted September 23 OPA Phoenix Technologies is currently building the large TI99/22 Project. It is the first complete reproduction prototype for the Texas Instruments TI99 Console and today we assembled the Unicorn Board which is small device using the ESP32 to emulate the original Console GROMs. 2 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 24 Share Posted September 24 I recently had the pleasure of sitting down with the wonderful folks at BeyondTrust and their amazing crew that produces The Adventures of Alice and Bob podcast. Have a listen and remember to support my GoFundMe at https://gofund.me/7bb6585b Many thanks! 🕹️ 1 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted September 25 Share Posted September 25 OPA is getting there 16-bits per cycle! Today, I setup a HD webcam mount and a ring light so my next TI99 building video will have an amazing close-up overview shot of my handy-dandy soldering skills. Also the wonderful "The 99000 Microprocessor - Architecture, Software, And Interface Techniques" textbook by Avatar Singh & Walter A. Triebel finally arrived, this will help refresh my 55 year old human sponge, so that my brain will be more focused, when I start soon designing new hardware and coding the upgraded TI Operating System. And finally, the open air backplate chassis for the 99/22 project arrived, and everything fits nicely on the 17" x 13" frame, since I am going to be working on various new add-ons and modifications, I don't need a full enclosure on this first prototype build. Plus all the parts arrived now to complete the Tang Nano 20k which will be used to replace the original TMS9918 with an FPGA version of the V9958 and giving the new TI a nice crisp HDMI video out. Stay tuned to this retro Texas Instruments channel as next up will be building the custom mechanical keyboard for this project, and we see how the new recording setup works! 5 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted October 1 Share Posted October 1 Adventures in Floppy Flux Forensics Using the amazing Greaseweazle device, we at OPA today were able to recover so far, 9 thirty-year old TI99 floppies containing thousands of TMS9900 Source Code files for our unreleased Phoenix RAMOS 2001 software and it's various utilities. 6 Quote Link to comment Share on other sites More sharing options...
+dhe Posted Tuesday at 09:54 PM Author Share Posted Tuesday at 09:54 PM @Gary from OPA -- RamOS9 - looks pretty complete. How close were you to a release? Were you able to get source code or only object code? 2 Quote Link to comment Share on other sites More sharing options...

Were you able to get source code or only object code? There is object and assembled versions as well. I ran some quick tests but. Found two bugs so far, a lockups in the 80 column mode on the f18a console and lockups when doing catalog directories on the tipi. Most likely the disk marked final which I recovered was bug free in 1994. But since then alot of new hardware exists, so will have to go through the code and make sure it's compatible with the current generation of hardware out there before I make any release.

+dhe Posted Tuesday at 11:44 PM Author Share Posted Tuesday at 11:44 PM I was really, REALLY looking forward to this release in about '00. And I'm still looking forward to it, 24 years later! I'm glad that the source code wasn't lost, like so much other code. What could be fairly easily done with the source to TI-Artist and TI-Base with modern hardware. 3 Quote Link to comment Share on other sites More sharing options...
